问题

  1. 我正尝试使用以下代码运行一个应用程序，使用acquiadevdesktop：
  3.      Process p1 = Runtime.getRuntime().exec("C:\\Program Files (x86)\\DevDesktop\\AcquiaDevDesktop\\AcquiaDevDesktop2.exe");
  4.             pb.start();
  5.             Desktop.getDesktop().open(new File("AcquiaDevDesktop2"));
  6.         } catch (IOException ex) {
  7.             Logger.getLogger(HConnexion.class.getName()).log(Level.SEVERE, null, ex);
  8.         }
  10. 但是我遇到了以下错误：
  12.     java.lang.IllegalArgumentException: 文件：AcquiaDevDesktop2 不存在。
  13. 	at java.desktop/java.awt.Desktop.checkFileValidation(Desktop.java:367)
  14. 	at java.desktop/java.awt.Desktop.open(Desktop.java:427)
  15. 	at DataBase.HConnexion.run_wamp(HConnexion.java:88)
  16. 	at DataBase.HConnexion.connectDb(HConnexion.java:35)
  17. 	at DataBase.DBcontrol.creer_piece(DBcontrol.java:105)
  18. 	at pdr.FrontController.initialize(FrontController.java:160)
  19. 	....
  21. 我可以尝试什么来解决这个问题？

  6.     }

Yet I am getting this error:

  1. java.lang.IllegalArgumentException: The file: AcquiaDevDesktop2 doesn't exist.

What can I try to fix it?

得分: 1

确保添加文件类型，因为new File()无法假设文件类型。

例如，如果是文本文件，应为：new File("AcquiaDevDesktop2.txt"));

英文:

Make sure to add the filetype, because new File() can't assume what type it is.

For example, if it's a text file, it should be: new File("AcquiaDevDesktop2.txt"));
